Pet owners are being warned of a virus outbreak which can be deadly to dogs.

The Cibyn Veterinary Clinic in Caernarfon said there have been cases of parvovirus in the local area.

Symptoms can include vomiting, profuse diarrhoea which is sometimes bloody with a strong odour, lethargy and anorexia.

The vets' clinic urged the public to ensure their pets' vaccinations are up to date and to take care walking their dogs.

Parvovirus is passed from dog to dog through contact with their contaminated faeces, but the virus will not infect humans.
